as mentioned, a friend of mine does an annual party that would be ideal on a party bus and can contribute a bit to purchase via rental.

personally, i'd like to see "modules" that can move in and out. something like mount unistrut rails on the walls, and be able to swap in and out a few seating options, work benches, tables, bunks, room dividers, etc so that it could vary between a camper, empty shell, party bus, or wood shop.
